Hmmm, you probably don't have that cake anymore. It depends what type of cake it was and where you kept it. If it has cream in it, I would put it in the fridge and it should last a few days, probably not a week.

Hi there. Well, I bought a Chinese cake on Sunday, and I have no idea how long it will last until it isn't good to eat anymore. I'm planning to wait a week, and I wanted to know that if within a week, will it still be good or no? The topping is white icing with strawberries and peaches. I would attach a photo if you guys want to look at it. Thanks!!
